Abstract (en)
[origin: EP1560243A2] A heavy duty relay (1) can safely switch a current of 40 A to 1 kA. The heavy duty relay is provided with a changeover spring (3) which can be resiliently deflected by means of a switching force (C) and with a normally-open contact (6), against which a contact point (5) of the changeover spring (3) is electrically conductively pressed in a switching position. The normally-open contact (6) is arranged on a normally-open spring contact (4), which exhibits a higher spring stiffness than the changeover spring (3) and is resiliently deflected in the switching position, and the changeover spring (3) and/or the normally-open spring contact (4) comprises a deflection region (18b) at least partially surrounded by a weakened zone (18a). The spring stiffness of the deflection region (18b) is reduced relative to the region of the changeover spring (3) and/or the normally-open spring contact (4) surrounding the weakened zone.
